您也可以使用未记录的通配符来实现此目的。

IF EXIST "D:\*Backup*.<" (
   ECHO "file exist"
) ELSE (
   ECHO "file not exist"
)

在以下两个链接中详细讨论了此通配符选项和其他选项。http://www.dostips.com/forum/viewtopic.php?t=6207

从这些链接：

The following wildcard characters can be used in the pattern string.

Wildcard character  Meaning

* (asterisk)
Matches zero or more characters

? (question mark)
Matches a single character

" 
Matches either a period or zero characters beyond the name string

>
Matches any single character or, upon encountering a period or end of name string, advances the expression to the end of the set of contiguous >

<
Matches zero or more characters until encountering and matching the final . in the name

使用此命令;它适用于任何特定模式：

set "fileExist="
for %%a in (d:\*Backup*.*) do set "fileExist=1" & goto continue
:continue
IF DEFINED fileExist (
   ECHO "file exist"
) ELSE (
   ECHO "file not exist"
)

这是另一种选择。

dir d:\*back*.* /b /a-d >nul 2>&1
if errorlevel 1 echo files exist

*.*相当于dos中的*。它只是表示“任何东西”，而不是“任何东西-句点-任何东西”。
要检查目录，请尝试以下操作：

IF EXIST D:\*Backup*\ (
   ECHO "directory exist"
) ELSE (
   ECHO "directory not exist"
)
